Lipoid pneumonia is a rare pulmonary disorder having no classical radiological appearance. We report a 33-year-old male, ex-smoker who was referred to us with history of cough, mild mucoid expectoration and progressively increasing dyspnoea since one year. He was investigated at local hospital and was treated with 30 mg prednisolone per day for 6 months for sarcoidosis without any response. On examination, he was normal except for fine basal crepitations in chest. Pulmonary function test (PFT) revealed mild airway obstruction. High resolution computerised tomographic scan (HRCT scan) revealed bilateral reticulonodular shadows and bronchiectasis in lower zones. Open lung biopsy revealed lipoid pneumonia. As there was no history of nasal distillation of oils, it was diagnosed to be idiopathic. The relevant literature is reviewed.

Lipoid pneumonia is a rare disease resulting from the micro-aspiration of lipid formulations. Making a diagnosis of lipoid pneumonia requires a high degree of clinical suspicion. Herein, we report the case of a female patient with a history of breast cancer, presenting progressive dyspnea and cough, together with radiological findings of bilateral pulmonary infiltrate. The working diagnosis of lymphangitic carcinomatosis, for which chemotherapy would be indicated, was called into question based on the high-resolution computed tomography findings and on the fact that the patient had a history of chronic ingestion of laxatives containing mineral oil. A lung biopsy confirmed a diagnosis of lipoid pneumonia, which should always be considered in patients with diffuse lung disease having been exposed to potential causative agents.

Exogenous lipoid pneumonia is a rare disease that has traditionally been considered a chronic condition secondary to continued aspiration or inhalation of fatty substances. An acute form may sometimes appear after a single and massive aspiration of lipid material, being a characteristic accident of street artists or "fire-eaters" that may generate acute respiratory failure. In this paper, we present clinical and radiological signs and outcome of two cases of lipoid pneumonia in "fire-eaters". A few hours after exposure patients may develop fever, cough, chest pain, hemoptysis, pulmonary infiltrates or hypoxemia. While diagnosis of chronic forms may require invasive procedures, recent exposure to fatty substances is a clue for clinical diagnosis in acute forms. Acute forms usually have a good outcome but cases evolving to cavitary pneumonia have been described. Some patients can present with acute respiratory distress syndrome and death. Treatment is based on general supportive measures.

Three patients with exogenous lipoid pneumonia are presented. All of them had laryngectomy because of the cancer of larynx. In a period of time ranging from a few months up to a few years after the operation they started to have dyspnoea, cough, sometimes hemoptysis and slightly elevated temperature. The chest X-ray revealed massive opacities in the lower zones of both lungs suggesting lung cancer or metastases of the laryngeal cancer. HRCT showed ground glass lesions. Histological examination of the lungs detected accumulation of multiple macrophages with vacuolated foamy cytoplasms in the alveoli. Neoplastic disease was excluded. Additional data from the patients history revealed that all of them were inhaling or administering mineral oil-containing products through the tracheostomy. Exogenous lipoid pneumonia was diagnosed. Patients were asked to stop inhalations with the mineral oil.

Lipoid pneumonia, first described by Laughlen 1925 may be classified as endogenous or exogenous. The endogenous form is seen when fat is deposited into the lung tissue. It is usually associated with proximal obstructive lesions, necrotic tissue after radio- or chemotherapy, with lipid storage disease or hyperlipidemia . Exogenous lipoid pneumonia results from inhaling or aspirating animal, vegetable or mineral oil. There are usually some underlying neurological defects or esophageal abnormalities. Patients may present with cough, sputum, hemoptysis and chest pain or may be asymptomatic. There is no classic chest film appearance: it may appear as diffuse airspace infiltration or localized consolidation simulating tumour. Computed tomography is diagnostically helpful and shows hypodense areas measuring from -100 to - 30 Hounsfield units. Bronchoscopic biopsies are mandatory for histological confirmation of the diagnosis. Treatment of exogenous lipoid pneumonia has always been conservative by discontinuing the use of oil, correction of underlying defects that may favor aspiration and treatment of intercurrent pneumonia. Other measures, for example corticosteroid therapy, are of uncertain benefit. Complications of lipoid pneumonia that worsen prognosis are recurrent bacterial pneumonias including nontuberculous mycobacteria or aspergillus, or lung cancer that has developed in areas of pre-existing exogenous lipoid pneumonia.

Lipoid pneumonia is an uncommon disease caused by the presence of lipid in the alveoli. It is classified into two major groups, depending on whether the lipid/oil in the respiratory tract is from an exogenous (exogenous lipoid pneumonia) or endogenous/idiopathic (endogenous lipoid pneumonia) source. The usual presentation occurs with insidious onset and nonspecific respiratory symptoms such as dyspnea and/or cough. The main radiological findings include airspace consolidations, ground-glass attenuation, airspace nodules and 'crazy-paving' pattern. However, the radiological appearance of the disorder can mimic many other lung diseases, including carcinoma. Owing to the nonspecific clinical presentation and radiological features, the diagnosis is often missed or delayed. Pathologically, lipoid pneumonia is a chronic foreign body reaction to fat, characterized by lipid-laden macrophages. Diagnosis of this disease requires a high index of suspicion and can be confirmed by demonstration of lipid-laden macrophages in respiratory samples such as sputum, bronchoalveolar lavage fluid or fine-needle aspiration cytology/biopsy from lung lesions. Treatment protocols for this illness are poorly defined.

Lipoid pneumonia is a rare medical condition, and is usually classified into two groups, ie, exogenous or endogenous, depending on the source of lipids found in the lungs. Exogenous lipoid pneumonia may result from the aspiration of food and lipids. Although most cases are asymptomatic, common symptoms include cough, dyspnea, chest pain, pleural effusions, fever, and hemoptysis. Radiologically, lipoid pneumonia can manifest as consolidations, pulmonary nodules, or soft-tissue densities. These presentations involve a wide differential diagnosis, including lung cancer. Other rare causes of fatty pulmonary lesions include hamartomas, lipomas, and liposarcomas. The avoidance of further exposures and the use of corticosteroids, antibiotics, and lavage comprise the mainstays of treatment. The exclusion of mycobacterial infections is important during diagnosis, in view of their known association. Generally, acute presentations run a benign course, if promptly treated. Chronic cases are more persistent and difficult to treat. Although the radiologic and pathologic diagnosis is fairly reliable, more research is needed to clarify the optimal treatment and expected outcomes. We report on a 54-year-old man presenting with progressively worsening cough, hemoptysis, and dyspnea over a few weeks. The patient underwent multiple computed tomographies of the chest and bronchoscopies. All failed to diagnose lipoid pneumonia. The diagnosis was finally established using video-assisted thoracoscopic surgery. Most of the paraffinoma was resected during this surgery. He was treated with antibiotics and steroids, and discharged from the hospital in stable condition.

Lipoid pneumonia is an unusual and uncommon form of pneumonia caused by aspiration of fatty substances. Hydrocarbon pneumonitis following aspiration of diesel is a form of exogenous lipoid pneumonia wherein, aspirated diesel reaches the alveoli rapidly without evoking any significant cough, but initiates an intense inflammatory reaction in the pulmonary parenchyma. This is a rarely described clinical scenario, although the practice of diesel siphonage from automobiles is a common practice in developing countries. We herein describe a 40-year-old male patient, in whom the diagnosis of lipoid pneumonia was delayed for a long duration and highlight the importance of taking a detailed occupational exposure history in patients with non-resolving pneumonia to rule out the underlying possibility of this rare clinical entity.

Lipoid pneumonia is an uncommon disease caused by the presence of lipid in the alveoli. Here we described a case of a 50-year-old woman with haemoptysis, cough and tachypnea, who was diagnosed with cholesterol pneumonia accompanying with pulmonary artery hypertension. The extremely high pulmonary artery pressure achieved, in this case, is alarming and should alert the physicians that the cholesterol pneumonia may be one of the underlying causes of pulmonary artery hypertension. After a treatment of methylprednisolone, her clinical symptoms were significantly improved, which suggested that steroid might be a promising therapeutic for patients with cholesterol pneumonia.

Lipoid pneumonia is an uncommon disorder characterized by accumulation of lipid components into the interstitial and alveolar compartment. The usual classification distinguishes endogenous and exogenous and acute or chronic forms, related to the type of fats, the amount of damage and the time of exposure. We describe a case of exogenous lipoid pneumonia by inhalation of vaseline used for cleaning of the tracheostoma in a 63-year-old female, presenting as cough, worsening dyspnea in few weeks. The diagnosis was finally established with a re-evaluation of BAL with specific staining for lipids, revealing the presence of foamy macrophages lipids rich, according to HRCT findings.
